We live in a wooded area in the foothills a couple miles from an urban area. It is a popular area for people to dump cats that they decide they don't want. We put food out on our back porch for the stray cats and raccoons. This cat hung around for several months before he made friends. We were trying to find a home for him because I am allergic to most cats.
He turned out to be a Siberian and they have less allergens than other cats, so it turned out that he does not bother me much so we let him live inside with us. When we first saw him, he was a normal sized cat, but it turned out that he was only a few months old. We have had him for about a year and now weighs 18 pounds. The vet said that he probably is not through growing. So, he still has all his kitten energy. The little drones are definitely his favorite toys. When he catches one, I have to wrestle it away from him before he chews it up.
Unfortunately, they don't make his favorite $20 toy drone anymore. Luckily it uses inexpensive batteries that are available for other toys and cost about $3 a piece.

18 lbs and still a kitten, that cat is going to be a lot of fun when he grows up! I took in a stray kitten that turned out to be a Maine Coon who grew up to be 20 lbs! My favorite Cat I ever had, he was a joy!
